It is very gentle indeed. Personally i've come to conclusion that computers are better at managing threads than i am, just like compilers are, for many decades now, better at managing CPU registers. It can definitely be enjoyable to ponder on some threading puzzle, now and then, but I very much prefer higher level abstractions like CSP or STM. Threads are not for human consumption.
